Determine method for tracing.
Background technology
With the progress of science and technology, the strategic propulsion of the developing of information technology, national " informationization " and smart city
Construction, the definition of video camera constantly rises, and cost is constantly reduced, and monitoring network has been dispersed throughout each corner of society, such as
Obtaining key message in the massive video information what is quickly and efficiently produced from monitoring network turns into urgent problem to be solved.Public security
Criminal policeman is usually requiring to scan for some specific objective in substantial amounts of monitor video during handling case, such as to violating
Guilty suspect and the search to vehicle, in traditional search procedure, to target be searched through human eye complete, it is necessary to
Substantial amounts of human resources, and degree of accuracy of its search can reduce with the degree of fatigue of people, therefore set up one kind and can search for automatically
The system of specific objective seems particularly significant in video.
Prior art is all in real time saved in video image all the time in the storage devices such as hard disk, video-tape, in case
Later retrieval, which returns to look into, waits application, but this larger memory space of needs.Although with the development of memory technology, the storage of Large Copacity
Equipment can preferably solve this problem, but in view of view data, which inherently has, takes the more defect of byte, therefore i.e.
It is the storage device that regardless of expense uses Large Copacity, it is also difficult to preserve all video images in longer period of time.
Prior art carry out Video content retrieval return look into when, it is many by the way of manually returning and looking into, namely adopt
With playing preserved video, and artificial judgment is carried out to video, look into mode inefficiency and easily slip for this time.People
Work is returned when looking into manually, and the speed of video playback can not be too fast, otherwise target object be likely to a sudden strain of a muscle i.e. without being noted, because
This section of 10 hours video, normal speed carries out back being accomplished by or so 10 hours if looking into from the beginning to the end, and is likely to
Significant video content only has several seconds or tens seconds, therefore efficiency is very low.And looked into for artificial return, Hui Cha
Personnel are watched during video for a long time, and notice can not keep concentrating for a long time, it is easy to fatigue be produced, so even being
Return and look into by normal speed, be also likely to appearance and slip and miss relevant information.For its shot using static camera
The video image that his application scenarios are obtained, there is also it is same the problem of.
